Abstract
The Pursuit Meter II was used with two input devices, a finger-controlled knob and an arm-controlled steering wheel, to test the hypothesis that fine pursuit-tracking performance could be differentiated from coarse pursuit-tracking performance. 26 Caucasian, right-handed, male college students were assigned randomly to a four-way crossover design. During each of the four weekly sessions a subject was tested on a set of 3 problem patterns at 45-min. intervals. Depending on the treatment assignment, each pattern was repeated either 5 or 10 times per session. Analysis indicated that pursuit-tracking performance was significantly better with the finger control than with the steering control. The difference between hand and steering was greater on the more complex patterns. Performance improved between sessions and between intervals within each session.
